Say my name, say my name! Reese Witherspoon doled out important advice to Cara Delevingne after the Met Gala on Monday, May 5. In new Instagram videos posted—and promptly deleted—by the British supermodel on Thursday, Witherspoon was seen fiddling with her phone and being her friendly self.

A subsequent Instagram video posted by Delevingne, 21, featured Witherspoon, 38, attempting to pronounce the model's name. "I love you Caara, Car-a," the sassy blonde said to the willowy It Girl. "I don't know what your f---ing name is," Witherspoon joked, as she slowly pronounced, "Del-e-ving-ne."

Witherspoon then quipped, "The most important thing for a name for a girl is that a man can whisper it in his pillow." Clearly not offended by Witherspoon's flub, Delevingne captioned the hilarious video: "I ??U @reesewitherspoon #wisewords #loveitwhenyousaymyname #cheeky."
